DETAILED DESCRIPTION The following description is specifically referringto the use of the present invention in relation to the control of atelevision receiver. However, the invention is not to be limited to aparticular type of receiver.

Before proceeding further. the term remote control device whichindividually controls the selection of one among a plurality ofcircuits" is specifically defined relative to the following descriptionas a remote control which operates in a manner as to be capable ofsending the same numbers of independent signals as there are numbers ofavailable television broadcasting channels.

For instance, a first controlling signal 0" may be transmitted to thetelevision set for controlling the channel selector of the set so as totune in the desired broadcasting channel A. In the same manner, anothercontrolling signal 17" may be transmitted to the set for controlling thechannel selector so as to tune in another desired broadcasting channelB. In general, each controlling signal corresponds to a specifiedbroadcasting channel thereby providing independent selection among theplurality of channels.

Concerning controlling signals, two embodiments will be disclosedhereinafter, one of which is a signal having a discontinuouspredetermined number of pulses and the other a signal having acontinuous wave for a predetermined period of time.

In the application, the first unit pulse received at the remotecontrolled set is used for resetting the channel selector or a tuner toa standard channel. and then the channel selector is adjusted so as totune in the desired channel in predetermined order of the number ofpulses received.

For example. assume that the third switch of the signal generatorcorresponding to the third selectable channel of the set is pressed totransmit remote control signals including three pulses.

The first pulse out of the three pulses would reset the channel selectorto a standard channel such as the first channel and the following twopulses would shift the channel selector to the second channel and thento the third channel in that order.

Since the entire shifting operation is completed in a very short time,it visually appears as if channel three were selected simultaneouslywith the manual pressing operation of the third switch of the signalgenerator.

The channel selecting process in the set is different in the operationwherein continuous pulses of predetermined relatively long signals areused.

In this case, the counted value of the continuous pulses is convertedinto a proportional DC voltage which controls the capacity of a variablecapacitor or some other variable impedance element. Such a control maybe a tuning circuit installed in the channel selector.

Referring now particularly to FIGS. I and 2, which show fundamentalblock and circuit diagrams, a channel selector circuit 11 includeschannel selecting switches SI, S2, S3 S10, each of which correspond to aselectable broadcasting channel in a television re ceiving set which isto be tuned in remotely and a decimal-binary converting Matrix circuit13. The selector circuit functions so as to produce indicating signalsto activate the power holding circuit 15 and power supplying circuit 17and to set the counting period of the preset counter circuit 19.

The preset counter 19 starts to count output pulses of the clock-pulsegenerator 21 when an indicating signal is supplied to it from delaycircuit 23.

After the counting period set by decimal-binary counting matrix 13,which is proportional to the binary output value, is completed, thepreset counter circuit 19 provides a stopping signal for controllingpower holding circuit I5, which consists of a modified flipflop circuitdesigned to control power supply circuit 17. Being triggered by theoutput signals of channel selector circuit II, the output of the powerholding circuit 15 which has two voltage states becomes high levelvoltage state until said circuit 15 receives the stopping signal fromthe preset counter circuit 19, and the high level voltage statemaintains the power supply circuit 17 to operate.

Being provided the stopping signal from the circuit 19, the output ofthe power holding circuit 15 becomes low level voltage state, and itmaintains the power supply circuit l7 not to operate.

In order to operate the system with some delay after the channelselector circuit 11 has been activated so as to prevent undesiredvibration or chattering, the delay circuit 23 is provided.

A pulse train from clock-pulse generator 21 is applied to a conventionalgate circuit 25 which is controlled by the output signal of delaycircuit 23. The output pulse train of gate circuit 25 activates theremote control signal generator 27 such as an oscillator which generatesultrasonic waves.

Before proceeding with a description of the operation of FIG. 2, itshould be noted that a positive logic system is used for convenience ofthe explanation. A negative logic system could also be adapted for suchuse.

Assuming that the switch S3 of channel selection circuit II is turnedon, the switch arm 10 is connected with a common earth terminal, biasingboth diode DI and diode D2 in that orderv Accordingly, a DC current pathexists from DC voltage source B+ biasing dividers R1, R2, and diode D2,a differential circuit and the diode DI, when switch S3 is released.switch arm 10 is connected with the DC voltage source 8+ and diodes D1and D2 are reversely biased which turns off the DC current path.

When switch S3 is in the closed position, a negative pulse is induced atthe positive pole of the diode D1, shown in FIG. 3 (a) as binary I).When switch S3 is open, a binary I condition exists. At the negativepole of the diode D2, a trigger signal FIG. 3 (b) which is sharper thanthe pulse shown in FIG. 3 (a). is derived because of the function of thedifferential circuit 29. The first transistor T1 is designed to operateunder the threshold voltage Vth in FIG. 3 (b). With the help of biasingdividers RI, R2, transistor T1 is activated during the period of *t" andsupplies DC current through the other divider R3, R4 activatingtransistor T2 which supplies DC voltage power (+Vcc) to all othercircuits such as NAND circuits N1, N2, N3, and N4 in the channelselector circuit 11, the clock-pulse generator 21, the preset countercircuit 19, power holding circuit 17, delay circuit 23, and the gatecircuit 25.

In order to keep DC voltage power supply to all circuits after one ofthe switches such as S3 is pressed. the power holding circuit I5 whichconsists of flip-flop circuit, is triggered by the same triggered pulseas shown in FIG. 3 (b) and keeps the transistor T3 activated so as tocontinue supplying DC voltage power until the stopping signal frompreset counter 19 resets the flipflop circuit again.

When the third switch S3 is closed under these power suppliedconditions, a 0 pulse is applied to these NAND circuits N, and Nrespectively, and consequently a I I binary value, which is 3 indecimals, is added to preset terminals U (2") and U (2) of the presetcounter in the form of a I pulse.

In this embodiment the preset counter 19 has only four preset terminals,U, (2"), U (2), U, (2 and U,, (2") and can be preset up to IS indecimals. However, it is to be understood that the number and capacityof the preset counter could be designed so as to meet functionalrequirements.

The output pulse 1 of the flip-flop circuit, which forms power holdingcircuit I5 is also applied to delay circuit 23, such as the pulse delaycircuit which derives a delayed pulse as shown in FIG. 3 (c).

It is noted that the delaying period A T is determined by consideringthe period of chattering or unwanted vibration of the whole system whichmay occur just after the unit pulse is introduced when one of theswitches is closed.

The delayed pulse P,,, FIG. 3 (c) activates the clockpulse generator 21for generating a clock-pulse as shown in FIG. 3 (d). This starts thepreset counter 19 for commencing the number clockpulses applied tocounting terminal H and the gate circuit 25 as a gate controllingsignal. Such control is applied simultaneously for purposes ofsynchronization. The gate circuit 25 passes applied clockpulses as longas the de- Iayed signal continues as shown in FIGv 3 (f) so as toactivate the remote control signal generator 27 in synchronization withthe applied clock pulse.

FIG. 3 (g) shows synchronized discontinuous ultrasonic waves transmittedby said generator 27. When preset counter I9 counts out the presetbinary value I I, as in the example above, it derives a stopping signal.S,,, as shown in FIG. 3 (1'). which resets flip-flop circuit of thepower holding circuit I5 and, in turn, disenergizes transistor T;,.

Consequently, the current path along the biasing divider R,. R is cutoff and transistor T and, subsequently, transistor T becomenon-conducting, thus terminating the power supply to all of thecircuits. It will be easily understood that, following a similarprocess, a pulse-train of ultrasonic waves. which has the number ofpulses corresponding with the number of the switch selected in thechannel selector circuit l I, will be transmitted by the remotecontrolling signal generator 27.

FIG. 4 discloses a slight modification of FIG. I. In this embodiment,the clock-pulse generator 3] consists of a free running multivibrator orother oscillator of the similar type which has a positive feedbackcircuit in which a gate circuit or AND circuit (not shown) is insertedand is controlled by the delay circuit 23, regardless of the powersupplied condition. Such a multivibrator is well known and commerciallyavailable.

FIG. 5 shows a block diagram of another embodi ment of the presentinvention wherein the delay circuit 23 is omitted and the power holdingcircuit is designed to be directly activated by the output signal of thechannel selector circuit 11, and the gate circuit is controlled by thestopping signal derived from the preset counter I9. In operation, whenswitch S is activated (FIG. 2). as in the example mentioned above, adifferential signal, as shown in FIG. 6 (a), of the pulse induced in thechannel selector 1] triggers a flip-flop circuit of the power holdingcircuit 15 in turn applies a controlling signal, as shown in FIG. 6 (h),to the power supply circuit 17 supplying operational power (Vcc to allof the circuits except power holding circuit IS. The function andoperation of the preset counter l9 and the clock-pulse generator 2I arethe same as previously described except that both of them are activatedby the output pulse of the power holding circuit I5 instead of thedelaying circuit 23, FIG. 2, and the stopping signal from the presetcounter I9 controls the gate circuit 25, instead of the delay circuit23. Operational wave forms at several parts of the block diagram in FIG.5 are shown in FIG. 6.

The fourth embodiment of the present invention is disclosed in FIG. 7 asa circuit block diagram and in FIG. 8 as schematic circuit diagram inwhich both the delay circuit 23 and the gate circuit 25 are omitted.

The only exceptions in the operation are that both preset counter I9 andclock-pulse generator 21 are designed to be triggered by the outputpulse from the flipflop circuit forming power holding circuit 15 which,in turn, is triggered by the differential output pulse, as shown in FIG.9 (b), FIG. 9 (u), induced by the channel selector 1 l, and is reset bythe stopping signal S,,, FIG. 9 ((1). received from the preset counterl9, when it has counted out the preset binary value.

In this embodiment, clock-pulse generator 2] which is controlled by saidpower holding circuit 15, driver remote control signal generator 27directly. The fifth embodiment of the present invention is shown in FIG.I0 in the form ofa block diagram and in FIG. 1] in the form of aschematic circuit diagram.

The distinguishable feature of this embodiment is clearly shown in theFIG. I2 U) which shows the continuous wave form of the remotecontrolling signal transmitter.

The period of the remote controlling signal is determined depending onthe number of the switch selected in channel selector circuit 11. Forthis purpose the remote control signal generating circuit 27 is designedto be driven by the delay circuit 23 which delays the pulse derived atthe power holding circuit 15 for a predetermined period.

The length T of the output pulse at the delay circuit 23 as shown inFIG. I2 (c) varies depending on the individual selecting function inorder to distinguish one remote controlling signal from another.

In this embodiment the length of each pulse mentioned above is designedsuch as shown in the following example.

When first switch is closed T, 30 in sec.

When second switch is closed T 50 m sec.

When third switch is closed T m sec.

A schematic circuit diagram relating to a sixth embodiment of thepresent invention is disclosed in FIG. 13. This embodiment has a specialfeature for preventing misoperation of the signal generator caused bychattering noise at the time of activating and deactivating the switchin the channel selector circuit.

It should be noted that a wave shape circuit 33 is inserted between thedelay circuit 23 and a comparison circuit 35 for preventing thechattering noise mentioned above.

The function of both wave shape circuit 33 and comparison circuit 35will be fully understood from the following explanation of operation.

In operation, when the third switch S of the channel selector circuit isturned on, a pulse of negative polarity is induced at the positive poleof the diode D, as shown in FIG. 14 (a) in the same way as in FIG. 2,and at the negative pole of the diode D a sharp pulse trigger is inducedas a differential form of the pulse as shown in FIG. I4 (12).

The pulse trigger is then applied to the first terminal 42 of NANDcircuit N which forms a part of the flipflop circuit 37.

During the period in which the pulse trigger falls down below thethreshold level Vth, FIG. 14 (b). the input signal of the first terminal42, of the NAND circuit N maintains O and the output signal I is appliedto the delay circuit 23 and to the second input terminal 40 of the ANDgate 47 which forms a part ofa compar' ison circuit 35.

On the other hand, when the continuous 0 pulse, which may containchattering noises Cd as shown in FIGS. I4 (a), is applied to the firstterminal 48 of the NAND circuit N and, in addition, the input pulsesignal at the second terminal 49 of the NAND circuit N is kept 0 (exceptfor the duration of the antichattering signal in FIG. I4 (e), which isexpected to be applied to the terminal 49 from the wave shaping circuit33) the logical output of the NAND circuit N becomes I. This output isapplied to the first terminal 41 of the AND circuit 47 making its outputI which is also the output of the comparison circuit 35. The output I isapplied to the first terminal 43 of the NAND circuit N which is a partof the flip-flop circuit 37. The second input signal applied to terminal44 is kept I until the stopping signal, as shown in FIG. l4 (c) S,,, isapplied thereto. Then the output 0 of the NAND circuit N causes theoutput signal of NAND circuit N,, to remain l, whether the other inputsignal becomes or I.

The output signal I of the NAND circuit N maintains the transistor Tconductive to complete a DC current path along DC power source (+13),biasing divider R, R diode D and the common earth terminal maintainingboth transistor T and T also conductive thereby supplying DC power +Vccto all of the circuits until the stopping signal from the preset counter19 resets the flip-flop circuit 37.

As mentioned before, chattering noises are observed at the descending Cd and the ascending C parts of the pulse induced by the channel selectorcircuit, H0. 14 (a) and these noises are differentiated by thedifferential circuit 29 which may possibly trigger the flip-flop circuit37. in the event the whole signal generator misoperates so as to sendunintentional signals as shown in dotted line in FIG. 14 (g) and (h),unintentional remote controlling signals, as shown in H0. 14 (i) S aretransmitted to the TV set to be controlled remotely.

In order to prevent the misoperation mentioned above, theanti-chattering signal, which is the wave shaped signal of the ascendingpulse at delay circuit 23 formed by the wave-shaping circuit 33, FIG. 14(e), signal A is applied to the second terminal 49 of the NAND circuitN-,. The operation will be more clearly understood by referring to thefollowing explanation. When the triggering pulse C caused by thechattering noise C activates the flip-flop circuit 37, the power supplycircuit operates in the manner described above. The pulse C is alsoapplied to the delay circuit 23 which derives a delayed signal D whichis, in turn, converted into the anti-chattering signal A,. at thewave-shaping circuit 33.

The anti-chattering signal A is applied to the second terminal 49 of theNAND circuit N whose first terminal has an input of I when the switch Sin the channel selector circuit 1 l is in off position. Therefore, atthe time when the signal level of the anti-chattering signal A, risesabove threshold voltage Vth (l in logic) the output signal of the NANDcircuit N becomes which resets the flip-flop circuit 37 and subsequentlycontrols the power supply circuit to stop supplying DC power to all thecircuits in order to prevent possible misoperation. Although theanti-chattering signal A,, is induced at the ascending position of thedelaying pulse P in normal operation, it should be noted that the pulseP as 0 from the channel selector circuit I1, is applied to the firstterminal 48 of the NAND circuit N which makes a l output with or withoutthe chattering signal at its second terminal 49 and no interferringproblem will occur.

The above remote control device may be used with a television set whichitself has individual switches for channel selection. One such set isproduced by SANYO, Model No. -R802. Such a set has individual variablecapacitors which correspond with each tuning circuit related to eachtelevision channel. The output signal of the present remote controldevice activates these tuning circuits.
